Meaning – Access control in the realm of computer security, is the process of ensuring that the classified files of an organisation, are only accessible to employees and admins who have the necessary clearance. The process of access control also exists on a personal level, where you can restrict access to certain files, if you are using a multi-user PC.
The act of accessing data corresponds to viewing, editing, or in some cases, even downloading or saving it on a different device. Organisations and individuals around the world employ the process of access control, to maintain a level of secrecy around confidential data, and this in turn reduces the risk of data leaks and further undesirable consequences.
Example of usage – “Data can only be accessed by managers and the CEO, as the organisation employs a strict access control policy.”
